• Cosmic tomography with weak gravitational lensing Research output

  We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

• Weighing the Dark: Cosmological Applications of Gravitational Lensing Research output

  Promotor: K. Kuijken, Co-Promotor: H. Hoekstra

• Galaxy alignments from multiple angles Research output

  Galaxies form and live inside dark matter haloes. As a consequence, they are exposed to the tidal fields generated by the surrounding matter distribution: this imprints a preferential direction to the galaxy shapes, which leads to a coherent alignment on physically close galaxies, called intrinsic a…

• Lights in a sea of darkness: constraining the nature and properties of dark matter using the stellar kinematics in the centres of ultra-faint Research output

  Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

• On a quest to discover where stellar-mass black holes merge: testing the AGN binary formation channel with spatial correlation analyses Research output

  The physical origin of the dozens of stellar-mass binaries, the mergers of which have been detected by the LIGO-Virgo-KAGRA collaboration via gravitational waves, is still unknown.

• Light Weighed: On the Statistics and Systematics of Weak Gravitational Lensing Research output

  In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

• About NIMAR The Netherlands Institute Morocco

  The institute is funded by the Ministries of Education, Culture and Science and of Foreign Affairs and by Leiden University. To safeguard the institute’s independence and interests in Morocco, it is part of the Netherlands Embassy in Rabat under Moroccan law. The institute performs its tasks under the…

• The alignment of galaxies across all scales Research output

  Galaxy intrinsic alignments induce a major astrophysical contamination to weak gravitational lensing measurements and need to be modelled and mitigated when extracting cosmological information from such measurements.
